Evenly distribute the selected animation keys in the «Graph Editor» along the X axis and separately along the Y axis

Advantage / application uniform distribution of animation keys:

1. Quickly evenly distribute animation keys of harmonic oscillation vertices by timing.
2. Quickly make a smooth transition through an even distribution of adjacent animation keys between two adjacent gait or run cycles.

There is already a variant on the site from the author "Markus von Broady" of a uniform distribution on all axes "Key Frame" and "Value" at the same time for "rotation euler Z". And do it for any curves. One button for uniform distribution of the selected animation keys on the "Key Frame" axis, the second button for distribution on the "Value" axis
